Perfect Camera Except for the Barrel Distortion Problem

I discovered a problem with this camera after 2 days of owning it. For the first 2 days, I thought I bought a prefect camera. I really enjoy the stylish look of this camera. It is small and easy to use. It has a big 3" screen and color quality is excellent. It always give me a bright picture. Until I discovered that all the pictures with buildings and interior walls, windows and doors got distorted. All the straight vertical walls had slight arch to it. A rectangular window will become a barrel shape window.

This might because the camera has a wide angle lens. When I zoomed in the image, the vertical condition will improve. But it is still bothersome to me that the outcome of the image is not represent the real thing. The other problem that I have this camera and my old Canon s400 is when the pictures are taken with flashlight, sometime I can spot 1 or 2 small bubbles of light in the picture. However, my major concern is the barrel distortion.
